This article paradoxically tries to come closer to an idea of justice with the help of the destructive — anything but nihilistic — criticism thereof by Hans Kelsen. It argues that his relativistic approach, in which this idea undergoes a metamorphosis to become a realisable value of a social order, brings us closer to an obvious and objective form of justice that is almost taken for granted. Just in our liberal and plural democracy this approach might prove to be of more value than a transcendental theory that passes speculative judgements on the essence of absolute justice, about which we are unable to come to an agreement.
